OK, if any of you guys are looking to root your sm-g530az just to get your tethering to work after 5.1.1 lollipop update, here is my own hack method I figured out for your stock phone, go to "settings" then "more networks" then "mobile networks" then "access point names" also known as "APN" create a new 1, then--
"NAME" - whatever name u want, I used "HOTSPOT"
"APN" - "ndo"
"PROXY" - "proxy.cricketwireless .net "
"PORT" - "80"
"USERNAME" - "PASSWORD" - "SERVER'" - leave blank.
"MMSC" - "http :// mmsc.aiowireless .net " NO SPACES
"MULTIMEDIA MESSAGE PROXY" - "proxy.aiowireless.net"
"MULTIMEDIA MESSAGE PORT" - "80"
"MCC" - "310"
"MNC" - "150"
"AUTHENICATION TYPE" - leave blank
"APN TYPE" - "default,mms,hipri,supl,fota"
Then save it....
Now if u change your APN to the new 1 u just created, then u can go back to your mobile hotspot and tethering, it WILL turn on "no extra charge" now your hotspot will have internet and most of your apps will also, except for internet explorer, so now that your hotspot is turned on, go back to your APN's and change it back to your original APN, opposite of the 1 u just made, "while your hotspot is still running" and now u should have mobile hotspot working and your internet explorer at the same time!
